TL;DR: Recurrent awakenings, threatening dreams, thrashing movements during sleep, and awakenings with startle or panic features represented the most prevalently reported sleep-related symptoms in combat veterans with PTSD.
Abstract: Objective: Sleep disturbances are important features of posttraumatic stress disorder (PTSD); however, the published data characterizing PTSD sleep phenomena are limited. The authors report on the phenomenology and physiological correlates ofsymptomatic sleep events in PTSD. Method: The study data included survey results that addressed sleep symptoms during the past month in combat veterans with and without PTSD (N-_58), sleep diary records of awakenings from combat veterans with PTSD hospitalized on an inpatient rehabilitation unit (N=52), and overnight polysomnography recordings obtained from 2 1 medication-free combat veterans with PTSD and eight healthy comparison subjects not exposed to combat. Results: Recurrent awakenings, threatening dreams, thrashing movements during sleep, and awakenings with startle or panic features represented the most prevalently reported sleep-related symptoms. Laboratory findings of longer time awake, micro-awakenings, and a trend for patients to exhibit body and limb movements during sleep are consistent with the subjectively reported symptom profile. Prospectively assessed symptomatic awakenings featured startle or panic symptoms or anxiety related to threatening dreams. Laboratory findings revealed a trend for the symptomatic awakenings (with and without dream recall) to be disproportionately preceded by REM sleep, and the two recorded awakenings with objective physiological arousal were preceded by REM. Conclusions: PTSD features intrusions into sleep of more highly aroused behaviors and states, which appear partially conditioned to REM sleep. (Am J Psychiatry 1995; 152:110-115)

TL;DR: A new clinical syndrome, sleep apnea associated with insomnia, has been characterized and an important clinical implication is that patients complaining only of insomnia may be suffering from this syndrome.
Abstract: A new clinical syndrome, sleep apnea associated with insomnia, has been characterized. Repeated episodes of apnea occur during sleep. Onset of respiration is associated with general arousal and often complete awakening, with a resultant loss of sleep. An important clinical implication is that patients complaining only of insomnia may be suffering from this syndrome.

TL;DR: The results suggest that sleep disturbances and, possibly, elevated resting heart rate, in middle-aged men, are associated with an increased risk of diabetes.
Abstract: OBJECTIVE —Sleep deprivation in healthy men has been experimentally found to result in disturbances in glucose metabolism and in sympathovagal imbalance. The aim of the present study was to investigate whether sleep disturbances and elevated resting heart rate are associated with increased risk of developing diabetes. RESEARCH DESIGN AND METHODS —A group of 6,599 initially healthy, nondiabetic men aged 44.5 ± 4.0 years took part in a prospective, population-based study in Malmo, Sweden. The incidence of diabetes during a mean follow-up of 14.8 ± 2.4 years was examined in relation to self-reported difficulties in falling asleep and resting heart rate at baseline. Diabetes was assessed at follow-up in all subjects by questionnaire and in a subgroup of 1,551 men by blood glucose measurement. RESULTS —A total of 615 (9.3%) subjects reported either difficulties in falling asleep or regular use of hypnotics (seen as markers of sleep disturbances), and 158 (2.4%) subjects reported both of these. Altogether, 281 (4.3%) of the men developed diabetes during the follow-up period. Logistic regression models showed difficulties in falling asleep or regular use of hypnotics (odds ratio [OR] 1.52 [95% CI 1.05–2.20]) and resting heart rate (OR per 10 bpm 1.13 [0.99–1.30]) to be associated with development of diabetes when full adjustments were made for baseline age, biological risk factors, lifestyle, family history of diabetes, and social class. CONCLUSIONS —The results suggest that sleep disturbances and, possibly, elevated resting heart rate, in middle-aged men, are associated with an increased risk of diabetes.

TL;DR: There is a high prevalence of sleep disorders and of excessive daytime sleepiness in subjects with TBI and there is a clinical indication for NPSG and MSLT.
Abstract: STUDY OBJECTIVES: Determine prevalence and consequences of sleepiness and sleep disorders after traumatic brain injury (TBI). METHODS: Prospective evaluation with polysomnography (PSG), multiple sleep latency test (MSLT), Epworth Sleepiness Scale (ESS) and neuropsychological testing including Psychomotor Vigilance Test (PVT), Profile of Mood States (POMS), and Functional Outcome of Sleep Questionnaire (FOSQ). SETTING: Three academic medical centers with level I trauma centers, accredited sleep disorders centers, and rehabilitative medicine programs. Participants; Eighty-seven (87) adults at least 3 months post TBI. Measurements And Results: Abnormal sleep studies were found in 40 subjects (46%), including 20 (23%) with obstructive sleep apnea (OSA), 10 (11%) with posttraumatic hypersomnia (PTH), 5 (6%) with narcolepsy, and 6 (7%) with periodic limb movements in sleep (PLMS). Among all subjects, 22 (25%) were found to have objective excessive daytime sleepiness with MSLT score or =30, p Language: en

TL;DR: The results suggest that the CSHQ is clinically useful for screening of sleep problems in typically developing children at these young ages as well as in children with diverse neurodevelopmental diagnoses.
Abstract: :Objective:Twenty to 40% of young children are reported to have behavioral insomnias of childhood. Concerns about sleep at these ages are the most common problem expressed to pediatricians at the time of well child visits. A screening questionnaire, the Children's Sleep Habits Questionnaire
